This was raised recently by Simon Coveney and also by Cork Chamber CEO Conor Healy:

Going forward, Cork has to have some sort of light rail solution if is to continue growing. The main issue at present is the massive dispersal of the population and thus the need for so many car commuters. Especially considering the continued construction of houses in Carrigaline, Midleton, Carrigtwohill, Ballincollig, Blarney designed wholly for car commuters. Constructing a light rail system may open up more areas of the city and will hopefully reverse the trend of everyone living in the satellite towns and commuting in by car.
What's yer opinion on it? Is it viable?
